WOW gold still a multi-million dollar business for them for several years.
There is no exception in wow gold. Since players discovered that they can make money by farming gold in wow gold and selling it to other players, a number of farmers have used a few "underground" methods to generate wow gold and sell it for real money. In order to get more money, hack skill was used in this industry.While in my mind, it is better to get wow gold by buying from online site rather than farm using hacks and cheats. Reasons are as follows:
When WoW first came out, it was full of bugs, and there were a few glitches present. Farmers with a sophisticated level of programming knowledge could sometimes discover exploits Blizzard were not aware of, and use these exploits to make a lot of wow gold very quickly. They could then sell this gold for a whole ton of real life money because the gold prices back then were high. Of course, with the abuse use of exploits, Blizzard noticed and banned any accounts they found taking advantage of the exploit. While for clever farmers, when they found this way is not feasible, they discover other skills. WOW gold still a multi-million dollar business for them for several years.
With the improvement of Blizzard's world of warcraft, WoW gold is no longer full of bugs like it used to be. Major exploits were naturally exploited to make huge gold, catching Blizzard's attention. The exploit would then be fixed and could no longer be used. Most major exploits have definitely already been discovered and patched. Nowadays, however, exploits and hacks are not nearly as effective as before.
The second reason is that wow gold prices have naturally gone way down. With over 500,000 gold farmers in China alone, there is a whole ton of competition between wow gold farmers, and this has driven the prices down dramatically.
Third reason, Blizzard paid much attention to hacks and cheats now, if you try any hacks or exploits now you'll risk getting your account banned. Blizzard has become much smarter and will easily notice if you are trying anything underhanded. They employ a team of people to monitor the games economy, and if they find some players are making huge amounts of wow gold and are causing prices to come down, then they will ban those accounts.
